Rails                   
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have  To Follow A Set Path. This Path Is 
 Called A  "Railway", Which  Is Comprised 
 Of Two Metal Rails,  Hence Its Nickname. 
                                          
 Because  The  Low  Friction Between  The 
 Wheels Of The Train And The Rail  Metal, 
 There  Are Limits For How Acute  A Curve 
 Can Be, And  Even More So For  How  Much 
 The  Ground  Under  The  Rails   Can  Be 
 Sloped. Thus A Railway  Is Often Not Led 
 On Top Of Hills, Rather  Through Them In 
 TunnelS   (If   They  Are   Large),   Or 
            Artificial ChasmS.            
                                          
 There  Will  Be Trees On The Side Of The 
 Rails, But Not  Too Close,  Or They Will 
 Be Cut  Down  By The  Railway  Janitors. 
 There Will  Be  Plains,  And  Bodies  Of 
                  Water.                  
                                          
 Trains  Go By Day And  By  Night.  Along 
       The Way, There Is Information      
 Scattered,  Often  Put On Top  Of Poles, 
 To Be Interpreted By The  Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
          Different Speed Limits.         
                                          
 Sometimes, Trains Have To Stop  And Wait 
 For Something To Happen,  Far Away. This 
 Is  Signaled  By Red  Or  Green  Lights. 
                                          
                                  
                                          
 Many  People Follow  The Rails  By Foot. 
 Often  This  Proves  To  Be  The Shorter 
 Path  Between Two Points.  However  This 
 Is  Frowned  Upon,  And   Very  Impolite 
        Toward The Train Drivers!
